Abstract

Disclosed is a storage device which communicates with a first external storage device and includes a deduplication manager. A method of operating the storage device includes broadcasting, by the deduplication manager, a first fingerprint of first data, receiving a first response corresponding to the first fingerprint from the first external storage device, determining, by the deduplication manager, whether a reference flag of the first response has a first value or a second value, updating, by the deduplication manager, first mapping information of a mapping table based on the first response, based on a determination that the reference flag of the first response has the first value, and performing, by the deduplication manager, deduplication of the first data, based on the first response, based on a determination that the reference flag of the first response has the first value.
